Description

Technical Field

[0001] The present invention relates to the field of diode manufacturing, and particularly to a device for removing glue channels from diode formed products. Background Art

[0002] When the formed product comes out from the inner end of the plastic packaging mold, the injection port of the product is connected to the body. The previous old process was as follows: Use a material rack to take the product from the upper end of the mold to the workbench, turn the material rack and the product over, press the product with the material rack, and use the hand to smooth the glue channel strips of the product and tear them off one by one. During the process of tearing the glue channel, the glue channel is often broken because the glue block becomes very brittle after plastic packaging curing and is easily broken. After the glue channel is broken, only sections can be picked out one by one, which is time-consuming.

[0049] The following specific embodiments illustrate the implementation manners of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification.

[0050] Please refer to Figures 1 to 7 . It should be noted that the structures, ratios, sizes, etc. shown in the drawings of this specification are only used to cooperate with the content disclosed in the specification for those skilled in the art to understand and read, and are not used to limit the limiting conditions for the implementation of the present invention. Therefore, they do not have substantial technical significance. Any modification of the structure, change of the proportional relationship, or adjustment of the size, without affecting the effects that the present invention can produce and the purposes that can be achieved, should still fall within the scope covered by the technical content disclosed in the present invention. At the same time, the terms such as "upper", "lower", "left", "right", "middle", and "one" cited in this specification are only for the convenience of clear description and are not used to limit the scope for the implementation of the present invention. The change or adjustment of their relative relationships, without substantial change in the technical content, should also be regarded as the scope for the implementation of the present invention.

[0051] The following various embodiments are only for illustration. Combinations can be made between the various embodiments, and it is not limited to the content shown in the following single embodiments.

[0052] Please refer to Figure 1 、 Figure 2 、 Figures 5 to 7 . The present invention provides an embodiment of a deburring device for a diode forming product, including: an upper pressing group 1 and a lower pressing group 2. The upper pressing group 1 includes an upper pressing plate 11 and a plurality of vertical knives 12. The vertical knives 12 are fixed on the lower surface of the upper pressing plate 11, and the vertical knives 12 are arranged at intervals; the lower pressing group 2 includes a lower pressing plate 21 and a plurality of bosses 22. The bosses 22 are fixed on the upper surface of the lower pressing plate 21. A first through groove 221 for the vertical knife 12 to pass through is provided along the length direction of the boss 22. The position of the first through groove 221 corresponds to the position of the vertical knife 12, and the first through groove 221 penetrates the upper surface and the lower surface of the boss 22; the lower pressing plate 21 is supported in a suspended manner, and one side of the lower pressing plate 21 is hinged to one side of the upper pressing plate 11.

[0053] The material rack clamps the formed products of the diode 3. One material rack is located on the lower side of the formed products of the diode 3, and the other material rack is located on the upper side of the formed products of the diode. When moving the formed products of the diode 3, it only needs to move the material rack. When it is necessary to remove the glue channel 4, the material rack places the formed products of the diode 3 on the lower pressing plate 21. Since the diodes 3 are arranged in parallel at intervals, there are continuous glue channels 4 perpendicular to the length direction of the diode 3. The glue channel 4 is located above the first through groove 221. When the vertical knife 12 is pressed into the first through groove 221, the vertical knife 12 cuts off the glue channel 4. Due to the spaced arrangement of the vertical knives 12, it can just avoid the position where the diodes 3 are located. In the direction perpendicular to the diode 3, multiple vertical knives 12 cut the glue channel 4 into multiple sections, and finally it falls from the first through groove 221. Then, the upper pressing plate 11 is turned upwards to remove the material rack above the formed products of the diode 3, and then the lower material rack is lifted to pour out the glue channel 4 remaining in the material rack. It will not damage the diode 3, nor will it bend the leads, and the working efficiency is improved. In addition, the vertical knife 12 cannot interfere with the diode 3, so a high positioning accuracy is required. Therefore, the upper pressing plate 11 and the lower pressing plate 21 are hinged, specifically, they can be hinged by a hinge. After the upper pressing plate 11 and the lower pressing plate 21 are hinged relative to each other, during the process of their combination, the vertical knife 12 can always be aligned with the interval between the diodes 3, so as to ensure the positioning accuracy and avoid damaging the diode 3. In this embodiment, the action of the upper pressing plate 11 pressing down on the lower pressing plate 21 can be manually operated. In order to facilitate the control of the upper pressing plate 11, a handle 111 can be provided on the upper pressing plate 11.

[0054] In this embodiment, please refer to Figure 3 , the vertical knife 12 includes a blade front surface, a blade back surface and two blade side surfaces, and the blade front surface, the blade back surface and the two blade side surfaces enclose the blade; the blade front surface or the blade back surface is an inclined surface, and the other surface is a straight surface. Optionally, one of the blade front surface and the blade back surface is a 45-degree inclined surface and the other is a straight surface; the blade side surfaces are both inclined surfaces, and an eight-shaped structure is formed at the blade parts of two adjacent vertical knives 12. The 45-degree inclined surface enables the blade to maintain a greater strength, and at the same time it can ensure that its sharpness can cut off the glue channel 4. The eight-shaped structure enables the blade part of the vertical knife 12 to more easily avoid the diode 3 when the vertical knife 12 is pressed towards the first through groove 221.

[0055] In this embodiment, the vertical knife 12 includes a blade front surface, a blade back surface and two blade side surfaces, and the blade front surface, the blade back surface and the two blade side surfaces enclose the blade; both the blade front surface and the blade back surface are inclined surfaces; the blade side surfaces are both inclined surfaces, and an eight-shaped structure is formed at the blade parts of two adjacent vertical knives 12. The eight-shaped structure enables the blade part of the vertical knife 12 to more easily avoid the diode 3 when the vertical knife 12 is pressed towards the first through groove 221. Optionally, the included angle between the blade side surface and the vertical direction is 3-5 degrees. In Figure 4In this case, the angle between the blade side face and the vertical direction is 4 degrees. The reason for setting it to 3 - 5 degrees is that on the one hand, it can avoid the diode, and on the other hand, it plays a transitional role. If the angle is too small, the avoidance effect is not good. If the angle is too large, when the blade side face contacts the diode 3, the force exerted by the blade side face on the diode 3 is relatively large and it is easy to damage the diode 3.

[0056] In this embodiment, please refer to Figure 1 and Figure 2 As shown in [relevant figures], multiple vertical knives 12 are linearly arranged in the edge direction to form a knife group, and the knife groups are linearly arranged perpendicular to the edge direction; each boss 22 is linearly arranged in the direction perpendicular to the length direction of the boss 22 to form a boss 22 group. Optionally, two groups of knife groups are arranged at intervals in the edge direction, and two groups of boss 22 groups are arranged at intervals in the length direction of the boss 22. A second through groove 222 is provided between the two groups of boss 22 groups in the direction perpendicular to the length direction of the boss 22. The second through groove 222 penetrates the upper surface and the lower surface of the lower pressing plate 21, and the second through grooves 222 communicate with each other. There are more glue channels 4 in the corresponding positions of the second through grooves 222. The connection between the glue channel 4 and the product is mainly at the corresponding positions of the first through grooves 221. Therefore, after the vertical knife 12 and the first through groove 221 cooperate to cut off the glue channel 4, the glue channel 4 corresponding to the second through groove 222 also separates from the product and can fall from the position of the second through groove 222. The purpose of the connection between the first through groove 221 and the second through groove 222 is that after the glue channel 4 is cut off, it can directly fall.

[0057] In this embodiment, please refer to Figure 1 As shown in [relevant figures], an embodiment of a device for removing the glue channel 4 from a diode 3 forming product further includes a rack positioning system. The rack positioning system includes side positioning columns 5 and intermediate clamping platforms 6. The side positioning columns 5 are used to position the four sides of the rack. The diode 3 forming product is clamped on the rack, and the intermediate clamping platforms 6 are used to position the middle part of the rack. Two side positioning columns 5 can be respectively arranged at the four corners of the lower pressing plate 21, and the intermediate clamping platforms 6 can be fixed to the bosses 22, that is, protruded in the direction perpendicular to the length direction of the bosses 22, with a hollow or concave structure corresponding to the intermediate clamping platforms 6 on the rack. The rack is a prior art and will not be elaborated here.

[0058] In this embodiment, please refer to Figure 1, a plurality of limit posts 7 are provided on the lower pressing plate 21, and the limit posts 7 are used to limit the extreme displacement of the upper pressing plate 11 pressing towards the lower pressing plate 21. When the upper pressing plate 11 presses towards the lower pressing plate 21, it is limited by the limit posts 7, and the height of the limit posts 7 can also be set in an adjustable form, making it convenient to adjust. That is, the pressing of the upper pressing plate 11 and the lower pressing plate 21 is positioned by the hinge structure on the one hand, and the extreme pressing degree is also positioned by the limit posts 7 on the other hand, ensuring that the vertical cutter 12 enters the interval between the diodes 3, and at the same time avoiding damage to the diodes 3 caused by excessive pressing.

[0059] In this embodiment, please refer to Figure 7 , the upper pressing group 1 and the lower pressing group 2 are installed on the vertical frame 8, and the flipping movement of the upper pressing plate 11 on the lower pressing plate 21 is driven by a linear driving member 9. One end of the linear driving member 9 is hinged to the vertical frame 8, and the other end of the linear driving member 9 is hinged to the upper pressing plate 11. That is, the movement of the upper pressing plate 11 pressing towards the lower pressing plate 21 realizes automatic driving. Through the hinge structure setting at both ends of the linear driving member 9, it can adapt to the hinge form of the upper pressing plate 11 and the lower pressing plate 21. The linear driving member can be a cylinder, a linear motor hydraulic cylinder, etc. In Figure 7 , a cylinder is adopted.

[0060] In this embodiment, please refer to Figure 7 , a first sensor 211 is provided on the lower pressing plate 21, and the first sensor 211 is used to sense the displacement of the upper pressing plate 11. The first sensor 211 can be inductive, capacitive, ultrasonic, etc. After the first sensor 211 senses that the position of the upper pressing plate 11 is in place, it transmits the information to the controller, and the controller controls the linear driving member 9 to stop extending, thereby realizing closed-loop control and improving the control accuracy. A stroke sensor 91 is provided on the linear driving member 9, and the stroke sensor 91 can be inductive, capacitive, etc. The stroke sensor 91 is used to sense the axial displacement of the output end of the linear driving member 9. The setting of the stroke sensor 91 enables the displacement of the output end of the linear driving member 9 to be monitored in real time and transmitted back to the controller, ensuring the accurate arrival of the output end of the linear driving member 9. The cooperation of the first sensor 211 and the stroke sensor 91 can realize the dual acquisition of the environmental data results, which has higher reliability. Cooperating with the limit posts 7 on the lower pressing plate 21, it realizes the positioning cooperation of the active output regulation and the passive mechanical limit, making the pressing degree of the upper pressing plate 11 and the lower pressing plate 21 accurately controllable, so as to better protect the diodes 3.

[0061] In this embodiment, in Figure 7In it, a collecting box 10 is further provided below the lower pressing plate 21. The collecting box 10 can collect the waste materials falling from the first through groove 221 and the second through groove 222. The collecting box 10 can be set as a movable structure to facilitate the removal of waste materials, and the vertical frame 8 can also be set as a movable structure.

[0062] In summary, through the cooperation of the vertical knife 12 and the convex platform 22 in the present invention, when the upper pressing plate 11 and the lower pressing plate 21 are pressed together, the vertical knife 12 passes through the glue channel 4 and inserts into the first through groove 221, capable of cutting off the glue channel 4 on the diode 3 and making it fall off. Moreover, during the cutting process of the glue channel 4, it can prevent the lead from being bent, and at the same time, it provides higher working efficiency compared with manual removal of the glue channel 4. Therefore, the present invention effectively overcomes various disadvantages in the prior art and has high industrial utilization value.

[0063] The above embodiments merely illustrate the principles and effects of the present invention, rather than limiting the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
